    Information and Notes

    1. IR700C,IR900C,IR970C(Cold Mirror) with 40~52 thin film layers which vacuum-deposited on substrate.

    2. Option: Side2 with multi-layer Anti-reflection coating to reduce reflection from 4% to 0.5% for less reflect of image or light.

    3. Coating by PVD-EBGE (Physical Vapor Deposition-Electron Beam Gun Evaporation) .

    4. The transmittance curves are measurements at 45°of incidence angle.

    5. The transmittance curves are based on actual measurements and may be different with manufacturing lots.

    6. IR720H,IR760H,IR780H,IR850H(Glass Filters) absorbing the light in orange and red wavelength range and transmitting light in the blue wavelength region.

    7. The transmittance curves are based on actual measurements and may be different with manufacturing lots.

    8. Glass Filters are also called "colored glass filters" or "color filters" generically.
